It has completed its 4 diamond drill hole program (total 2,318 m) at the Rudnitza copper-gold porphyry project located within the Suva Ruda exploration permit in Serbia. Tethyan has received assay results for the first drill hole RDD-001 with assays for the remaining 3 drill holes pending.

Tethyan drilled 567 metres at 0.28% copper and 0.45 g/t gold from surface in its first drill hole RDD-001. Detailed results are in the table below:

Drill hole RDD-001 from surface intersected a thick package of dacitic volcanic rocks showing strong phyllic and propylitic alteration with extensive zones of thin (2-20 mm) quartz - pyrite ± chalcopyrite veining and stockwork. Between 122 - 160 m, a 38 m chalcocite-bearing zone of supergene enrichment was intersected giving an interval of 38 m at 1.18% copper and 0.38 g/t gold, although copper grades were lower in the leached zone above this interval gold grades remain consistent averaging 0.45 g/t gold. From a depth of 160 m gold and copper grades are consistent up to the intersection of a deeper ophiolite basement rock-type which was intersected between 567 and 584.6 m and where the gold and copper grades reduced. The drill hole was terminated due to drilling issues at 584.6 m still in mineralisation.

The technical information in this document has been approved by Southern Arc's President & Chief Operating Officer, Dr. Mike Andrews, PhD, FAusIMM, who has sufficient experience relevant to the style of mineralization under consideration and qualifies as a Qualified Person as defined by National Instrument 43-101. Dr. Andrews has reviewed Tethyan's drill program and sampling protocol, and is of the opinion that the QA/QC data and sampling programs are acceptable.

The drill program and sampling protocol is managed by Tethyan under the supervision of Fabian Baker, BSc (Hons) Geology, Tethyan's Chief Operating Officer. Mr. Baker has 8 years of international mineral exploration experience in frontier and developing countries. During this time he has held such positions as Chief Geologist at Lydian International and Exploration Manager for Tigris Resources. The core recover rate at drill hole RDD-001 averaged better than 97.5%. Half core is cut by rock saw and is generally sampled using nominal 2 metre intervals; however, sample intervals are varied according to geological contacts and have ranged between 1.2 to 2.6 metres in length. Four quality control samples (one standard, one blank and two duplicates) are inserted into each batch of 40 samples. The half core samples are securely transported from the project site to the ALS Global sample preparation laboratory in Bor, Serbia via private truck provided by ALS Global to Tethyan. Sample pulps are then sent to ALS Rosia Montana, Romania by air freight for gold. Gold is analysed by fire assay with AAS finish and sent to ALS Loughrea, Ireland by freight for analysis by a four-acid digestion with ICP-AES finish to analyse a full suite of 33 elements including silver and base metals. ALS's laboratory is ISO 2005 accredited and employs a Laboratory Information Management System for sample tracking, quality control and reporting.
